Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of solar module installation, and in particular to a photovoltaic backsheet anti-scratch tool. Background Technology
[0002] Photovoltaic power generation technology converts light energy into electrical energy, making full use of nature's energy. Currently, single-glass modules are gradually gaining popularity due to their unique advantages. Compared to traditional double-glass bifacial modules, single-glass modules are lighter, effectively reducing the load-bearing requirements on support structures and other facilities during installation, thus lowering installation costs and complexity. Furthermore, under the same size conditions, single-glass modules offer superior power performance, bringing higher power generation efficiency to photovoltaic systems.
[0003] Single-glass modules often employ a three-layer backsheet structure consisting of glass and PVDF, PET, and another PVDF layer. However, modules with PET backsheets present several risks: misalignment during installation necessitates manual intervention, which is difficult to achieve precisely in terms of lead hole positioning. Direct contact between the lead metal surface and the backsheet can easily scratch the PVDF coating. Severe damage to the PVDF coating drastically reduces the module's corrosion resistance, significantly shortening its overall lifespan. Furthermore, for backsheets with a black inner layer and white outer layer, manual intervention after misalignment can easily scratch the black coating, leading to a downgraded appearance and reduced overall performance. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a photovoltaic backsheet anti-scratch tooling, thereby solving the module quality risk caused by coating scratches due to backsheet misalignment in single-glass modules.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a photovoltaic backsheet anti-scratch tooling, including a spherical protective device, a lead wire sleeve and a base; the spherical protective device is connected to the top of the lead wire sleeve, the lead wire sleeve is fitted on the outside of the lead wire of the photovoltaic module, the base passes through the lead wire and is installed at the bottom of the lead wire sleeve, and the base can fit in contact with the battery of the photovoltaic module.
[0006] Furthermore, the surface of the base is provided with a rubber layer, which is bonded to the cells of the photovoltaic module.
[0007] Furthermore, the spherical protective device is a PET spherical protective device.
[0008] Furthermore, the lead wire sleeve is a PET lead wire sleeve.
[0009] Furthermore, the base is a PET base.
[0010] Furthermore, the lead sleeve is a tapered lead sleeve.
[0011] Furthermore, the height of the lead sleeve is the same as the height of the lead.
[0012] Furthermore, the area of the base is not greater than the area of the photovoltaic module's encapsulant film holes and backsheet holes.
[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0014] 1. In the production process of photovoltaic modules, the photovoltaic backsheet can be accurately drilled with this utility model. Due to the presence of the spherical protective device, when the backsheet comes into contact with this utility model during the drilling process, the risk of scratches caused by the single glass backsheet being laid off can be effectively avoided, thereby ensuring that the quality and appearance of the photovoltaic module are not damaged.
[0015] 2. The height of the lead sleeve is designed to precisely match the height of the lead wire. This design effectively avoids misfitting after the utility model is put on, preventing it from falling off during the production process, thus ensuring that the utility model can always play a protective role.

[0020] The present invention will be further described below with reference to specific embodiments.
[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0022] See Figures 1 to 4 As shown, the photovoltaic backsheet anti-scratch fixture provided in this embodiment includes a spherical protective device 1, a lead wire sleeve 2, and a base 3.
[0023] The spherical protective device 1 is connected to the top of the lead wire sleeve 2. The spherical protective device 1 adopts a spherical design without sharp corners to better avoid coating scratches and facilitate personnel handling. The lead wire sleeve 2 is a conical lead wire sleeve 2, which is fitted onto the outside of the lead wire 6 of the photovoltaic module. The height of the lead wire sleeve 2 is the same as the height of the lead wire 6, which protects and fits the lead wire, effectively preventing the lead wire 6 from falling. The base 3 passes through the lead wire and is installed at the bottom of the lead wire sleeve 2. The surface of the base 3 is provided with a rubber layer, and the rubber layer of the base 3 can fit against the cell 5 of the photovoltaic module to avoid direct contact with the cell and cause cell breakage. The area of the base 3 is not greater than the area of the encapsulation hole and backsheet hole of the photovoltaic module. The spherical protective device 1, the lead wire sleeve 2, and the base 3 are integrally molded and are all made of PET material.
[0024] The method of using the photovoltaic backsheet anti-scratch fixture provided in this embodiment is as follows: The worker holds the anti-scratch fixture, aligns the lead sleeve with the lead 6, and then ensures the base 3 fits snugly against the cell 5 of the photovoltaic module. This completes the placement operation. During the photovoltaic module production process, the backsheet 4 can precisely drill holes into the anti-scratch fixture. Due to the presence of the spherical protective device 1, the risk of scratches on the backsheet is effectively avoided when it comes into contact with the anti-scratch fixture during the drilling process, thus ensuring that the quality and appearance of the photovoltaic module are not damaged. The base 3 is made of rubber and can fit snugly against the cell 5 of the photovoltaic module, providing stable support. The height of the lead sleeve 2 is designed to precisely match the height of the lead 6. This design effectively avoids misfitting after the anti-scratch fixture is applied, preventing it from falling off during production and ensuring that the anti-scratch fixture always provides protection.
[0025] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
